When I load up the FireRed ROM in VBA, it says the "1M sub-circuit board is not installed" stopping me from playing the game. Anyone know why this is happening (I've never used a GBA emulator before so I don't understand much about it)

Hello Nostalgia64. Options > Emulator > Save Type > Flash 128K. It should solve the problem :)

yeah, I figured it out after looking through the options a little OpieOP
